MCU Database

Neural Inverse ships with a pre-indexed database of 361 MCU variants. When you select an MCU, the IDE loads its complete hardware context — registers, memory map, peripherals, clock constraints, and known errata.

Searching the Database

Use the agent tool:

> fw_search_mcu cortex-m4 fpu 1mb flash

Or search by board name:

> fw_search_mcu nucleo

The search supports fuzzy matching on variant, family, manufacturer, core, peripherals, boards, and keywords.

What MCU Selection Activates

When you select an MCU (via Firmware.inverse, auto-detection, or manual search):

SVD register maps — All peripheral registers, bit fields, access types, reset values
Memory layout — Flash/RAM regions with addresses and sizes
Clock constraints — PLL limits, prescaler ranges, max frequencies
Errata database — Known silicon bugs with workarounds
GPIO AF database — Alternate function mapping per pin
Peripheral list — Available peripheral instances
System prompt injection — All hardware context injected into AI completions

Adding Custom MCUs

If your MCU isn't in the database, the project detector will still work if you have standard build system files. You can also specify the MCU details in your Firmware.inverse manifest with a custom SVD file path.
